/**
 * This is the interface that can be implemented by an application-provided

 * application can be notified by the DCPS Service of relevant status changes.
 * 
 * The purpose of the DomainParticipantListener is to be the listener of last
 * resort that is notified of all status changes not captured by more specific
 * listeners attached to the {@link DomainEntity} objects. When a relevant
 * status change occurs, the DCPS Service will first attempt to notify the
 * listener attached to the concerned DomainEntity if one is installed.
 * Otherwise, the DCPS Service will notify the Listener attached to the
 * DomainParticipant.
